Answer:

I think it's shape the shape of the samples

Answer: Answer is below <3 (The underlined part is the answer)

Explanation: The reason why an object with a smaller mass has a larger acceleration than an object with a larger mass if the same force acts on each is because the acceleration of an object depends on its mass as well as the force exerted on it, and if the mass is smaller than the other object than it is faster.

The reason why a football accelerates faster than a soccer ball when the same amount of force is applied is because of the difference in their masses. The acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that the smaller the mass of an object, the greater the acceleration it experiences when the same amount of force is applied to it.

A football is typically smaller and lighter than a soccer ball, so when the same amount of force is applied to both balls, the football experiences a greater acceleration due to its lower mass. This is consistent with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.

Additionally, the surface area and shape of the balls can also affect their acceleration. A football is typically more aerodynamic with a pointed shape that reduces air resistance, allowing it to move through the air more easily and accelerate faster. In contrast, a soccer ball has a more spherical shape that can create more air resistance, slowing down its acceleration.

Therefore, the mass, shape, and surface area of the ball are all factors that can affect its acceleration when a force is applied.

Answer:

the surface temperature of Regulus A is 11724.13 K

Explanation:

Given the data in the question;

Sun's surface temperature T = 5800 K

total radiated power, relative to the sun is; P/P\(_{sun\) = \((\) 1.5(M/M\(_{sun\) \()^{3.5\)

The star Regulus A is a bluish main-sequence star with mass 3.8M\(_{sun\)  and radius 3.1R\(_{sun\) .

First, we determine the value power emitted by the sun or sun as follows;

P = eσAT⁴

where P is the power, e is surface emissivity, σ is Stefan Boltzmann, A is area and T is temperature.

so, lets assume emissivity of star and sun is same;

let p be power related to star and p\(_{sun\) be power related sun.

Ratio of power radiated by star and power radiated by sun;

P/P\(_{sun\) = eσAT⁴ / eσA\(_{sun\)T\(_{sun\)⁴

we know that AREA A = πR²

we input the formula for area

P/P\(_{sun\) = eσ(πR²)T⁴ / eσ(π(R\(_{sun\))²)T\(_{sun\)⁴

such that we now have;

P/P\(_{sun\) = R²T⁴ / R\(_{sun\)²T\(_{sun\)⁴

given that P/P\(_{sun\) = \((\) 1.5(M/M\(_{sun\) \()^{3.5\), we substitute

\((\) 1.5(M/M\(_{sun\) \()^{3.5\) = R²T⁴ / R\(_{sun\)²T\(_{sun\)⁴

we find temperature of the star T

T = 5800  × \([\) 1.5\((\)M/M\(_{sun\)\()^{3.5\) (R\(_{sun\)²/R²)\(]^{1/4\)

Given that;  mass M is 3.8M\(_{sun\) and radius R is 3.1R\(_{sun\) .

we substitute

T = 5800  × \([\) 1.5\((\)3.8M\(_{sun\)/M\(_{sun\)\()^{3.5\) (R\(_{sun\)²/( 3.1R\(_{sun\) )²)\(]^{1/4\)

T = 5800  × \([\) 1.5\((\)3.8\()^{3.5\) ( 1/( 3.1)²)\(]^{1/4\)

T = 5800  × \([\) 1.5( 106.9652 ) ( 1/(9.61) \(]^{1/4\)

T = 5800  × \([\) 16.69592 \(]^{1/4\)

T = 5800  ×  2.02140152

T = 11724.13 K

Therefore, the surface temperature of Regulus A is 11724.13 K

Answer:

26m/s

Explanation:

Given parameters:

Initial velocity  = 18m/s

Time  = 2s

Acceleration  = 4m/s²

Unknown:

Final velocity

Solution:

To solve this problem, we use the expression below:

     Acceleration  = \(\frac{v - u }{t}\)

v is the final velocity

u is the initial velocity

 t is the time taken

    4   = \(\frac{v - 18}{2}\)    

      v - 18  = 8

       v  = 8 + 18 = 26m/s

The minimum mass required to be placed on the 0.00 cm mark of the meter stick to maintain equilibrium is 0.120 kg.

To maintain equilibrium, the torques acting on the meter stick must balance each other. The torque is given by the formula:

τ = r * F * sin(θ)

where τ is the torque, r is the distance from the pivot point to the point where the force is applied, F is the force applied, and θ is the angle between the force vector and the lever arm.

In this case, the meter stick is in equilibrium when the torques on both sides of the pivot point cancel each other out. The torque due to the weight of the meter stick itself is acting at the center of mass of the meter stick, which is at the 50.0 cm mark.

Let's denote the mass to be placed on the 0.00 cm mark as M. The torque due to the weight of M can be calculated as:

τ_M = r_M * F_M * sin(θ)

where r_M is the distance from the pivot point to the 0.00 cm mark (which is 30.0 cm), F_M is the weight of M, and θ is the angle between the weight vector and the lever arm.

Since the system is in equilibrium, the torques on both sides of the pivot point must be equal:

τ_M = τ_stick

r_M * F_M * sin(θ) = r_stick * F_stick * sin(θ)

Substituting the given values:

30.0 cm * F_M = 20.0 cm * (0.0400 kg * 9.8 m/s^2)

Solving for F_M:

F_M = (20.0 cm / 30.0 cm) * (0.0400 kg * 9.8 m/s^2)

F_M = 0.0264 kg * 9.8 m/s^2

F_M = 0.25872 N

Finally, we can convert the force into mass using the formula:

F = m * g

0.25872 N = M * 9.8 m/s^2

M = 0.0264 kg

Therefore, the minimum mass required to be placed on the 0.00 cm mark of the meter stick to maintain equilibrium is 0.120 kg.

Answer:

Explanation:

charge on each proton = 1.6 x 10⁻¹⁹ C

mass of proton = 1.67 x 10⁻²⁷ kg

Electrostatic force of repulsion Fe = 9 x 10⁹ x ( 1.6 x 10⁻¹⁹ )² / d²

= 23.04 x 10⁻²⁹ / d²

Gravitational  force of attraction = G Mm / d²

M = m = 1.67 x 10⁻²⁷ kg

Gravitational  force of attraction  Fg = 6.67  x 10⁻¹¹ x ( 1.67 x 10⁻²⁷ )² / d²

= 18.60 x 10⁻⁻⁶⁵ / d²

So Fg is far less than Fe and former is attractive , later is repulsive .

Fe > Fg, opposite direction , is the answer .

Measuring the distance from  \(I_1 \ to \ I_1'\) and dividing by 2 has advantage of achieving a more accurate result compared to measurement taking directly.

Measuring the distance from \(I_1 \ to \ I_1'\) is equivalent to the double of the distance.

This method of measurement gives a more accurate result because it minimizes error that may result from taking readings form the intervals. It ensures more accurate result compared to the measurement obtained when \(OI_1\) is measured directly.

\(OI_1 = \frac{I_1 + I_1'}{2}\)

Thus, we can conclude that measuring the distance from  \(I_1 \ to \ I_1'\) and dividing by 2 has advantage of achieving a more accurate result compared to measurement taking directly.

The diameter of the smaller end of the pipe is approximately 0.78 meters.

To determine the diameter of the smaller end of the pipe, we can use the principle of conservation of mass. According to this principle, the mass flow rate of water should remain constant throughout the pipe.

The mass flow rate is given by the equation:
Mass flow rate = density of water * cross-sectional area * velocity

Since the density of the water remains constant, we can write:
Cross-sectional area1 * velocity1 = Cross-sectional area2 * velocity2

Given that the velocity1 is 13 m/s, the diameter1 is 1.2 m, and the velocity2 is 30 m/s, we can solve for the diameter2 using the equation:
(pi * (diameter1/2)^2) * velocity1 = (pi * (diameter2/2)^2) * velocity2

Simplifying the equation:
(1.2/2)^2 * 13 = (diameter2/2)^2 * 30

Calculating the equation:
(0.6)^2 * 13 = (diameter2/2)^2 * 30

0.36 * 13 = (diameter2/2)^2 * 30

4.68 = (diameter2/2)^2 * 30

Dividing both sides by 30:
0.156 = (diameter2/2)^2

Taking the square root of both sides:
0.39 = diameter2/2

Multiplying both sides by 2:
0.78 = diameter2

Answer:

67.5km/hr

Explanation:

The average speed traveled is the total distance divided by the total time taken.

  Average speed  = \(\frac{total distance }{total time}\)  

   Distance  = speed x time

Time 1  = 2.5hrs

Speed 1  = 60km/h

    Distance 1   = 2.5 x 60  = 150km

Time 2  = 1.5hrs

Speed  2  = 80km/h

   Distance 2  = 1.5 x 80  = 120km

 Average speed  = \(\frac{150km + 120km }{2.5 + 1.5}\)   = 67.5km/hr

Answer:

Both cars convert more kinetic energy to thermal energy.

Explanation:

Given that,

Two cars come to a stop from the same initial speed, one braking gently and the other braking hard.

We know that,

The conservation of energy :  

The energy of the system is always constant.

The energy can be change one form to another form.

So, we can say that when both cars come to a stop from the same speed, one braking softly and the other braking strongly then both cars convert more kinetic energy to thermal energy.

Hence, Both cars convert more kinetic energy to thermal energy.

Based on the law of consevation of energy, the car that brakes hard will convert more kinetic energy to thermal energy.

According to the law of conservation of energy, the total energy is conserved in any closed system.

Since the cars have the same mass and had the same initial speed, their kinetic energies are the same.

However, the car braking hard comes to rest in a shorter time and in a shorter distance.

Using the formula for calculating power:

The car that braked hard will have greater power due to shorter time of action.

This power is seen as greater thermal energy, whereas some of the energy of the other car will still be used in travelling some distance before stopping.

Therefore, the car that brakes hard will convert more kinetic energy to thermal energy.

Answer:

5.67 m/s

Explanation:

The speed of a wave can be calculated as the distance traveled by the wave divided by the time taken:

Speed = Distance/Time

In this case, the distance traveled by the wave is the length of the pool, which is 17 m. The time taken by the wave to travel this distance is 3 seconds.

So, the speed of the wave can be calculated as:

Speed = 17 m/3 s

Speed = 5.67 m/s

Therefore, the speed of the water wave in the 17 m long pool is 5.67 m/s.
